Basically, this game is not actually supported, even though it appears in the Steam Library.

FTL developers have added Linux support on Steam for Linux if you participate in their beta - the password is "betapatch".
I quote marcusmoller. There is a beta version for Linux in Steam. Some people can download and play FTL, some other can't. Maybe is a 64bit version issue,
Once you’ve opted into the beta branch with the password, it will download the same FTL as you can get from their website, which includes both x86 & x86_64 bins.
Opted in, but it still didn't download anything.
@jidlaph:
Perhaps you could try to remove local content and then reinstall.
@marcusmoller I've tried but still doesn't work. :(
FYI: FTL was just added to the official supported game list. Please delete local content and download again.
Nothing extracted yet.
After installing "FTL: Faster Than Light" no download starts. When attempting to start the game, Steam gives the following error message:
"Failed to start game (missing executable)"
The message links to a non-existant helpdesk page.
